The [1,5]-anion relay/[2,3]-Wittig rearrangement of 3,3-bis(silyl) enol allyl ethers has been developed. This reaction provides an efficient method to synthesize versatile vinyl bissilanes, which can be transformed into trisubstituted vinylsilanes through a [1,4]-Brook rearrangement/alkylation protocol using a wide range of electrophiles.
已经开发了3,3-双(甲硅烷基)烯醇烯丙基醚的[1,5]-阴离子继电/ [2,3] -Wittig重排。该反应提供了一种合成通用的乙烯基双硅烷的有效方法,该乙烯基双硅烷可以通过使用多种亲电试剂的[1,4] -Brook重排/烷基化方案转化为三取代的乙烯基硅烷。
